Peter Rentrop MD Cardiologist, Medical Director The year 2023 is an important milestone marking two major developments in the history of cardiology. 2023 is the 45th anniversary of percutaneous coronary intervention (PCI), our present-day treatment of choice for heart attacks, which was performed for the first time by Klaus Peter Rentrop, MD, in 1978. PCI has substantially reduced the mortality of heart attacks and saved millions of lives worldwide. The second milestone is the 30th anniversary of the establishment of the American Society for Nuclear Cardiology in 1993, in which Dr. Rentrop became a founding member.
